Out of town, monitoring by thermostat/furnace history data. Device is set on ECO since this is an extended absence, and it's winter cold where I live, so heat mode only. On one particular day, the history data for the day before showed that my heating system was "on" for 24 hours uninterrupted. Yet the settings on the thermostat and current temperature inside, etc. were all normal. I remotely raised the temp, and the heating system responded ok, so after about 10 minutes I returned to ECO mode. The days before or after that day look like normal operation. I had someone check, the day after the funky data, and everything in the house was fine.
Wondering what this might be? I have a hard time believing the data was/is real?
